NLP corrections to Higgs+jet production

Next-to-leading power (NLP) corrections can leave a numerically
sizable impact on the differential distribution of cross sections in the
threshold limit. I'll discuss the computation of NLP corrections to the
Higgs plus one jet production in the hadron collider and show how the
shifting of spinors in the tree level helicity amplitudes can capture the
leading next-to-soft radiative behaviour. I'll explain a few interesting
consequences such as the connection between dipoles & colour-ordered
amplitudes, vanishing of next-to-maximal helicity violating amplitudes etc.
The final analytic expressions of NLP leading logarithms thus obtained are
simpler and compact.
